You do understand the meaning of that last sentence? It means my parents came to America for a selfish reason, as all immigrants do. Sure, the stated reason for most immigrants may be for economic betterment, to escape political repression, or flee religious persecution, and such. But, the ultimate motivating factor is always for the betterment of one’s self, and/or family. In other words, no immigrant has ever arrived at these shores in order to make America great. On the contrary, they came because they believed America was already great, and a land of opportunity.
